Front Panel
①Power LED: The LED illuminates green when power is applied.
②INPUT LED: The LED illuminates green when there is an input signal present.
③OUT 1 ~ OUT 2 LED: The LEDs illuminate green when there is an HDMI output
on the corresponding port.
Rear Panel
①IN: Type A female HDMI input port to connect an HDMI source.
②OUT 1 and OUT 2: Two Type A female HDMI output ports to connect HDMI
displays.
③AUDIO OUT: 3.5mm mini jack and 3-pin Phoenix plug for the de-embedded
analogue audio output.
④EDID: 4-pin DIP switch used for EDID setting.
⑤Pinhole button used for EDID setting.
⑥Micro-USB port for firmware upgrade.
⑦DC 5V: DC barrel port to connect a 5 VDC AC power adapter.
Notes:
a) Pictures shown in this manual are for reference only, different models may vary
slightly.
b) The Output HDCP compliant status depends on the input signal. When the input
signal has HDCP, then output signal has HDCP and vice versa.
c) HDMI signal contains both HDMI video signal and embedded audio signal (PCM,
Dolby Digital, DTS, DTS-HD), while the DVI signal contains only a video signal.
d) The AVG-UDA2 DA can switch input signal formats per the displays.
For example, when the input signal is HDMI and the display can only support a
DVI signal, the AVG-UDA2 DA will change the signal to the DVI format.
e) EDID Management: automatically manages the output signal (e.g. output
resolution) to fit all displays.

4.3 Connection Procedures
Step1. Connect an HDMI/ DVI source device (e.g. Blu-ray DVD) to the HDMI
INPUT socket of AVG-UDA2 DA with a HDMI cable.
Step2. Connect the HDMI displays to the HDMI OUTPUT sockets of AVG-UDA2
DA with HDMI cables.
Step3. Plug a DC 5V power adapter to the power port of AVG-UDA2 DA.
Note: All the ports support hot-plugging. It’s important to know that hot plugging a
display may result in a splash screen at the output ends.
4.4 EDID Management
The Extended Display Identification Data (EDID) is used by the source device to
match its video resolution with the connected display.
⚫Predefined EDID settings
The 4-pin DIP switch on the rear panel can be used to set the EDID to a fixed value.
Use the following table to determine the settings for the 4-pin DIP switch for specific
video resolution and audio capabilities. When in the lower (ON) position, each switch
represents “1”, it represents “0” when setting the switch in the upper position.

⚫EDID data transfer
Please follow the procedure as below to allow the source device to obtain its EDID
data from the display which is connected to the OUT 1 port:
1) Set the 4-pin DIP switch to status “1110”.
2) Connect the source device to IN port, and connect the display to the OUT 1 port.
3) Long-press the pinhole switch for at least five seconds on the rear panel until the
input LED blinks to indicate the splitter has entered EDID copy mode.
4) Once you have successfully copied the EDID data from the OUT 1 port to the
input source, the input LED will blink three times. If that fails, the copy process
will retry 5 times. If it still fails, the input LED will go out and the source device will
still save the previous EDID data.
4.5 Applications
Robust performance for signal transmission makes the AVG-UDA2 DA ideal in the
custom installation industry, IT computer space, signal monitoring, big screen
displays, conference systems, television broadcast, education, banking and security
institutions etc.
4.6 Firmware Upgrade
Please follow the steps as below to update the firmware using Micro-USB port on the
rear panel:
1) Connect the AVG-UDADA to your PC by USB cable, and then power on the
splitter. The PC will automatically detect a U-disk named of “BOOTDISK”.
2) Double-click the U-disk, a file named of “READY.TXT” would be showed.
3) Directly copy the latest upgrade file (.bin) to the “BOOTDISK” U-disk.
4) Reopen the U-disk to check the filename “READY.TXT” whether it automatically
becomes “SUCCESS.TXT”, if yes, the firmware was updated successfully. If not,
the firmware update failed, the name of upgrade file (.bin) needs to be checked
again, then repeat the above steps.
5) Remove the USB cable after a firmware update.
